Probably the genus Mimoneetes has its nearest relatives in the families Thauma- 

 topsidce and Lanceolidce, agreeing with them in the shape of the first pair of antenna; 

 and in the inflated perseon, which last character, however, is much more exaggerated 

 here than in the representatives of those families. The last five pairs of peraeopoda 

 are remarkably like those pairs of the true Hyperidce, showing that, how strange the 

 appearance of Mimoneetes may be, it, however, has a close connection with the typical 

 family of the tribe. 



A. The sphaerical portion of the body is formed of the head and the first five 



pergonal segments. The metacarpus of the first two pairs of perseopoda is 



almost conical, hirsute 1. M. Loveui. 



B. The spherical portion of the body is formed of the head and the first six pe- 



rgonal segments. The metacarpus of the first two pairs of peraeopoda is 



provided with a spinulous prominence on the hinder margin, not hirsute 2. 51. sphiericus, 



C. The spherical portion of the body is formed of the head and all the pergonal 



segments. The metacarpus of the first two pairs of peraeopoda is cylindrical, 



armed with long spines 3. M. Steenstrupi.

Diagn. Caput dimidio diametri sphaerae altius. Articulus primus flagelli antennarum primi paris pe- 

 dunculo plus quam duplo longior, crassus, serratus. Segmenta quinque prima percei 

 sphasram formantia. Metacarpus pedum percei primi et secundi parium fere conicus, hirsutus. 

 Pedes tertii paris tertiam partem diametri sphsera? lougitudine aequantes. Telson pedunculo 

 pedum uri ultimi paris multo angustius, et plus quam duplo brevius. 



The head is higher than half the diameter of the globe. The first joint of the nagellum of 

 the first pair of antenna is more than twice as long as the peduncle, thick, serrated. The 

 first five segments of the peraon form the globe. The metacarpus of the first two pairs 

 of perceopoda is almost conical, hirsute. The third pair equal a third of the length of 

 the diameter of the globe. The telson is much narrower than the peduncle of the last 

 pair of uropoda, and shorter than half the peduncle.
